ABSTRACT:
An elastomeric stator for an eccentric spiral pump is provided. The stator has a lining that is made of elastomeric material and has a hollow chamber that serves for accommodating a rotor. The hollow chamber has a double or multiple spiral configuration. A rigid casing surrounds the lining and both the casing and the lining have an essentially uniform thickness over their length. The casing is spiraled in conformity with an inner contour of the hollow chamber. A respective flange ring is secured at each end of the casing for resting against other pump parts. The flange rings are detachably connected to other pump parts without the use of tie rods.
